The choices of the video convert which i need to ?

I'm work in ICT running SAP Programs and like Golf, boating , fishing etc. On weekend, I always stay at home with my family. So, I need to find a Video Converter which used to store on NAS and played through Apple TV and Plex Software in the home. Also used to put onto Ipad when travelling.I have used Xilisoft software and DVDFab. Which one is best?

I used to use Handbrake, it's free, but the conversion effect was not so good. One of my guys recommended Pavtube Video Converter Ultimate to me and the when I use it, I really love it! Hope it will help you as well.
